Four members of British rock band Pink Floyd will play together for the first time in 24 years at London's Live 8 charity concert for Africa on July 2, publicists for the event said Sunday.

Guitarist David Gilmour, drummer Nick Mason and keyboard player Richard Wright will be onstage with bassist Roger Waters for their first public performance since they played at London's Earls Court in 1981. Waters, the group's creative force, quit in 1985 and unsuccessfully tried to prevent his band mates from using the Pink Floyd name.

The rock legends will join a star-studded lineup including Coldplay, Elton John and Paul McCartney at the Live 8 concert in Hyde Park, organized by activist rocker Bob Geldof to pressure rich nations to ease African poverty.

"Like most people I want to do everything I can to persuade the G-8 leaders to make huge commitments to the relief of poverty and increased aid to the Third World," Gilmour said. "Any squabbles Roger and the band have had in the past are so petty in this context, and if re-forming for this concert will help focus attention, then it's got to be worthwhile."

The band released its first album, "The Piper at the Gates of Dawn," in 1967 and broke records with 1973's "The Dark Side of the Moon," which remained on the American album charts for more than a decade.

After Waters left, Gilmore, Mason and Wright launched two hugely successful world tours. They released their last studio album, "The Division Bell," in 1994.
